IMPROVEMENT INBARRELLING GOCKS.

TO ALL WHOM IT MAY CNOERN:

Be it known that we, ALEXANDER MGKENNA, JOHN MeKnNNA, and THoMAs MGKENNA, of the city of Pittsburg, in the county o,f Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Barrelling (looks; and we hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming par't of this specification, and to the letters of reference marked thereon. v

The nature of our invention consists in-constructing a barrelling cock with a tapering nozzle to ,fit the bung-hole of a barrel, and furnished with openings for the escape of the air as the liquid passes in, and, in combination with the air-passage, a Whistle or other contrivance that will indicate by sound the flow of liquid While filling, and so constructed as that when the liquid in the barrel reaehes the noz'zle the sound will cease, whereby-` the person in charge may know that the barrel is full; also in providing the key of the coek with a large ring or handle to enable the operator to shut ofl' the flow and carry the eock in an easy manner from barrel to barrel, as occasion may require; also in holding and securing the key in the body of the coek by means of a set-screw passing through the body and entering a groove or channel in the key. v

l To enable others to understand and make our improvement, we will proeeed to describe it by reference to the accompanying drawings, wherein- Figure 1 represents a perspective viewlof our improred barrelling cook.

Figure 2 represents a longitudinal Vertical section of the same. Figure S is a cross-section`oiI the nozzle. All the 'drawings are lettered, and similar letters denote corresponding lparts in the several views. We construet a cock, of metal, and make it very similar in appearanee to'the ordinary cocks now in use, but in order to carry out the object we have in view, we lengthen the nozzle A, making it four or five inches long; and to voonform to the various sizes and shapes of bung-holes, it is made tapering on the outside, as seen in fig. 1.

` In the interior of this nozzle A, and to one side of the bore" C, is a small longitudinal projection, B, through whichav hole, 'Sg is drilled extending up to and communicating with another hole, T, passing diagonally through the key F. In the upper end of this 'hole Tis placed a small metalliewhistle, D, or similar contrivance, by which a sound may be produced as the air escapes from 'the barrel through the openings S T during the operation of filling. By this`` arrangement it will be seen thatwhen the liquid as it rises in the barrel reaches .the lower end of the nozzle A, it Will oover the mouth of the opening S and shut ofl' the air, when the sound will cease and indieate that' the barrel is full. This key F is held in place in the body H of the cock by means of a set-screw, L, the point of which enters a groove or channel, Nfpermitting the key to turn. The scr ew may be set at an angle to the axis of the key, as represented in fig 2. This position of the sorew not only holds the key in place, but tends to force it d'ownvas the key wears away. This cock is constructed for the purpose of drawing oif liquids from large tanks into barrels, and for that purpqse the short pipe J is corrugated that it may be more seeurely fastened in the end of a flexible hose leading from the tank; and to enable the person in charge to operate the cock and carry it from barrel to barrel, the upper end of the key F is'provided wi th a large ring or handle M, as seen at fig. 1.

Having thus briefly described our improved'barrelling eock, what we elaim,` isw i Combining with a barrelling cock, a whistle or other contryivance that will indicate by sound the flow of liquid while filling, and so coustructed as that when the liquid reaches the nozzle the sound will cease. whereby the person in charge may know that the barrel is full.
